Another way would be for each bug to keep data on its previous 
locations, e.g., in a list of objects that each contains a pair of 
previous X and Y coordinates. Then the bug could draw line segments 
between each of its past locations. In Swarm you would do it with this 
message to the raster:

- lineX0: x0 Y0: y0 X1: x1 Y1: y1 Width: penWidth Color: c
